How I use YouTube videos to learn anything about UE :
1. Skip to 2 minutes, intro is always fluff
2. Watch about 30 seconds on double speed to see if it looks worth it
3. Scrub around the video looking for the thing that looks relevant to the problem I have, or something I don’t recognise
4. Watch another 30 seconds to extract that one thing I was missing
5. Close the video not having watched about 90% of it
Better than watching the whole video but still worse than a blog post
